Specification of Letters Patent.

Patented June 26, 1906.

Application filed August 10, 1905. Serial No. 273,584.

To (LZZ whom it may concerni Be it known that I, HELMER H. ENGE-BRETSON, a citizen of the United States, residing at Albee, in thecounty of Grant, State of South Dakota, have invented certain new anduseful Improvements in Latches; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to door-latches.

One object of the invention is to provide an exceedingly simple,inexpensive, durable, and efiicient means for locking screen or otherdoors.

Another object of the invention resides in the provision of a lockembodying such characteristics that the screen or other door will lockautomatically u on closing of the same.

With these and ot er objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and articularlypointed out in the appended c aim, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claim without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is a view illustrating a portion of ascreen-door and a doorcasing, showing the manner of locking thescreen-door. Fig. 2 is a side elevation of the receiving portion of thelatch, partly in section, the door being shown in edge view.

Referring now more particularly to the accompanying drawings, thereference character 1 designates a portion of a door-casing to which oneportion of my improved latch mechanism is secured.

The receiving member of the latch consists of the members 2 and 3, themember 2 having upwardly-directed ears 4 at one end, between which themember 3 is pivoted by means of the pivot-pin 5. The lower member 2 isprovided with transverse perforations 5, through which are passed screws7 for the securing of the said member fixedly to the door-casing. Thislower member 2 is provided with a hole 8 near its outer end for thereception and support of a helical spring 9, which s ring is connectedwith the member 2 and t e lower face of the upper pivoted member 3 tohold the latter normally in engagement with the upper face of the lowermember 2. Formed in the u per face of the lower member 2 in advance 0the said hole 8 is a recess 10 for the reception of the depending lug 11of the up er pivoted member 3, there being another ug 12 depending fromthe said pivoted member 3 in advance of the aforesaid lug 11, said lugsforming a hook for engagement with the keeper on the door.

The reference character 13 designates a screen or other door, to theinner face of which the feet 14 and 15 of the latch-plate 16 are securedin any suitable manner. This plate 16 lies in a horizontal lane and isprovided with a short slot 17. pon closing of the door 13 the forwardedge of the plate 16 contacts with the beveled edge 18 of the pivotedmember 3, raising the latter against the action of the aforesaid spring9 until the lug 12 falls into the slot 17 of said plate, and therebyautomatically locks the door, the lug 11 positively preventing movementof the latch-plate inwardly between the members 2 and 3, and therebypositively insuring the engagement of the lug 12 in the slot of thelatch-plate. I A

What is claimed is- A latch comprising a receiving member and a platefor engagement by the receiving member, the receiving member comprisinga fixed member having a hole and a recess therein, a pivoted memberprovided with spaced lugs one of said lugs being ada ted for engagementin the recess of the ed member to limit the inward movement of the saidplate, and a spring arranged in the hole of the fixed member and engagedwith the mally in engagement.

In testimony'whereof I affix my signature in presence of two witnesses.
